My partner and I are trying to build an itinerary around a stay at a family friend's property in Mykonos (March 29-April 2). I know Mykonos will be very quiet this time of year, we are looking forward to the isolation and peace (we live year-round in New York City, and the property has a private pool overlooking the sea). We would like to add one more island after Mykonos (3-4 nights), along with a full day in Athens on the backend of the trip.
Given that this is barely shoulder season in the Greek Islands, I am looking for suggestions for one other island to visit after Mykonos. We were originally interested in Santorini (typical, I know), but we have heard how developed and commercial it has become. Then we found Milos, and are very interested in the authenticity of this island, the quiet fishing villages like Klima and Mandrakia, and the natural scenery and beautiful rock/beach formations. We would love somewhere with a touch of sightseeing, but mostly just nice landscapes, where we can enjoy a sunset with some wine at a restaurant/taverna, and walk around quaint towns (like Plaka). The worrying part is the lack of connectivity between Mykonos and Milos this time of year. I saw that indirect ferry routes are upwards of 24 hours in length, which just seems highly inconvenient for our schedule, or flights through ATH and back again.
We would so appreciate any suggestions for well-matched and efficient island pairings with our stay in Mykonos, specifically with our travel dates of April in mind! Thank you all very much!
